Abstract

In this paper, a PC-based virtual instrument (VI) for a power analyzer is developed. Instead of theoretical research, a practical VI that can be integrated into an existing VI system is developed. The functions of power analyzer developed in this paper include the harmonic analyzer and instantaneous power measurement. The proposed VI is based on the LabVIEW (Laboratory Virtual Instrument Engineering Workbench) language under the workbench of the MS Windows 95/98 operating system. The capability of the proposed method can be expanded according to the requirements of users. Some sub-VIs for the power analyzer are developed in this paper and the idea of software integrated circuit (IC) can be achieved by using these sub-VIs. All sub-VIs developed in the paper are free for noncommercial use.
